SOIL EROSION POLYMERSJRM Chemical offers a full line of quality and diverse linear anionic polymers for the professional in the erosionindustry. The products vary in molecular weight, charge density and form to perform in all types of soil/site condi-tions and applications in the erosion industry. Applications include but are not limited to: Construction and BuildingSites, Hydroseeding, Highway Construction, Mine Tailings, Refuse Sites, Reforestation and Revegatation. All prod-ucts comply and are certified with NSF International ANSI/NSF 60, drinking water. All products do not bioaccumu-late.

The linear compound polymers help maintain soil structure and reduce soil erosion. The anionic or negative chargelinear polyacrylamide/acrylic acid polymers are designed to flocculate discharge water. The sodium breaks from thepolymer chain (disassociates) once introduced to water and become a negative charge. The negative charged poly-mer will form a bridge with positive charged parts (divalent cation) of the suspended soils in the water and makelarger soil aggregates. Larger soil aggregates will settle to the bottom of the discharge water. The anionic polymerbonds soil particles along the discharge water channels and maintains soil erosion. When used in hydroseeding or asan over spray, the anionic polymer binds the hydroseeding media to the soil particles. For complete information onhydroseeding applications, refer to form 700/701.

BENEFITS AND FEATURES • Reduces soil erosion• Removes soil and clay particles from discharge water.• Eliminates colloidal solutions in discharge water when applied

directly to the discharge ditch• Improves soil by increasing soil porosity and water infiltration• Reduces fertilizer and pesticide loss• Improves site conditions and compliance with regulatory

requirements.

Pam Tablets are designed to reduce soil erosion, remove solubleparticles and reduce NTU values in water channel applications.The tablets are ideal on sites where electricity and machinery arenot available for metering, pumping or dispensing devices. Thetablet can be used on all water applications where there is turbid water. One important and distinct advantage of thetablets over large blocks/bricks and logs of polymer is their ability to release polymer in all water velocity flowrates, in particular low flow rates of turbid water. The surface area of the tablets is significantly higher than blocksand logs. The tablets release the polymer and do not "gel block" and become ineffective as larger sized blocks andpolymer logs can do.

Application: Prior to any application, perform a standard jar test to test the effectiveness of the product for the spe-cific site. There are many environmental and soil variables that effect the performance of the products. Place 20up to 40 tablets in the supplied nylon mesh bags. Use the higher range of tablets in the higher water flow applica-tions. Tie a not in the mesh bag 5-6 inches above the tablets. The extra space give the tablets more surface area totreat the turbid water. Note: In high water flow applications (> 100 gpm) tie the knot in the nylon mesh bag asclose as possible to the tablets. Stake and secure the nylon mesh bag as close to the source of the water flow andturbidity as possible. Place the mesh bag as close to the center of the water flow. In earthen channels and applica-tions of high turbidity, additional mesh bags should be evenly spaced (15 to 25 feet) in the first 20% of the channel.To increase the effectiveness and performance of the tablets, place a nylon mesh bags directly below drop inlets,rock checks and other obstacles in a channel that causes water turbulence. Periodically check site and replace sacksas needed.

Powders: Three powders commonly used in turbid water applications are the FIseries of linear anionic polymers, FI-1000, FI-1045 and FI-1046. Each anionicpolymer has a unique charge density, UL viscosity and molecular weight to treatvarious types of turbid water and site conditions. Another influential factor thateffects the performance of linear polymers in the field is the content of cation insoil. The FI-1000 series is better suited for sandy soils in turbid water while theFI-1045 and FI-1046 products are more suited for higher density soils and clays.Always perform a standard jar test to insure the effectiveness of theproduct with site conditions. For hydroseeding and temporary dustcontrol applications, refer to form 700/701.

These products are packed in plastic pails and are resistant toweather conditions in the field. They are supplied with a built inspout for ease of application.

Application: The powders can be used either alone or in conjunc-tion with the erosion tablets. In earthen water channels that will beused on an extended basis, if possible, line with 2-3 layers of jute.The jute mesh acts as a filter and increases the residual effect of thelinear anionic polymer. Apply 5 up to 20 pounds (use the higherrate with highly turbid water) along the first 20% of the source ofturbidity and flow of water. This initial treatment is used to "shock"the turbid water. The polymer should be reapplied after a fewheavy discharges caused from mechanical or natural (rainfall) occurrences.

When water is being pumped from the site to holding ponds prior to final discharge, a "split pipe system" is widelyused. Any diameter of plastic drain pipe is cut lengthwise in half. The pipes are then bolted together and patchedwith common roofing cement to keep water tight. Line the pipe with two to three layers of jute. Align the split pipefrom the water pump to the holding ponds. Slowly pour 5 to 20 pounds of polymer from the water pump down thefirst 20% of the split pipe.

Periodically check the water turbidity of the treated water and reapply as needed. Small concentration rates of poly-mer from .5 ppm to 3.5 ppm can greatly reduce the NTU values in water In closed drain applications, product shouldbe applied directly after the drop inlets or storm drains.
